Orange Widgets are building blocks of Orange's graphical user's interface and its visual programming interface. The purpose of this documention is to describe the basic functionality of the widgets, and show how are they used in interaction with other widgets.
Widgets in Orange can be used on their own, or within a separate application. This documention will however describe them as used within Orange Canvas, and application which trough visual programming allows gluing of widgets together in whatcan be anything from simple data analysis schema to a complex explorative data analysis application.
In Orange Canvas, widgets are grouped according to their functionality. We stick to the same grouping in this documentation, and cluster widgets accoring to their arrangement withing Canvas's toolbar.
The documentation refers to the last snapshot of Orange. The version you use might miss some stuff which is already described here. Download the new snapshot if you need it.
